That's fine, because the 300 part is normal, it's only the 21 part that's reversed. It's drei hundert ein und zwanzig. 

So only the last 2 numbers are reversed. 

That’s really interesting. How do you write 321 then?

Why you might be counting in the wrong language (2019)

Very interesting.

I speak German, and when dealing with numbers in German, (which is done like in old English, like one and twenty for 21, and so forth) I gotta do some work arounds to make it  make sense to me.

Usually I'll write the number out with my finger, the ones column first , and then the tens column to the left of it. Then I can "visualize it", in a way that makes sense.

Yes, a bit strange.
